Chapter 1: My Little Sister Can't Cooperate with a Railgun[edit]

Since this might be the first time some of you are meeting me, allow me to introduce myself. I'm Kousaka Kyousuke, a very ordinary high school student. Just now, if that introduction sounded familiar, please check out 'My Little Sister Can't Be This Cute' published by Dengeki Bunko.

Since the introduction is finished, let's move on to the main topic.

One day as usual, I came back home and saw my little sister talking on the phone while sitting on the sofa.

"Ah! Really! Sure, I'd love to!"

Sounded like she was talking about her work.

My little sister's name was Kousaka Kirino, she was working as a model, and her picture was on the cover of many magazines. Recently, starting with Chiba Monorail and Chiba Mazda, she had signed contracts with a variety of companies, so sometimes I saw her pictures on the street—so amazing! I really was impressed with her.

Truly, that was what I thought.

"Good, no problem. Then let's talk more about it the next time we meet!"

Kirino turned off her cell phone and laughed "A, hahaha...hahaha...~"

She looked very relaxed and slovenly.

Somehow, this girl suddenly made me feel annoyed.

"What's up?"

"Ah? Ah, you are back."

"I just came back."


Kirino showed me an arrogant look.

Well, that was normal, however—


She was drooling while texting, which looked quite disgusting.

"...Was the release date of new eroge decided?"

"Ha? Wrong wrong ~ Hmph ~ hmph~, what's wrong? Are you curious?"

Not exactly curious, it would be more accurate to say that I was wondering if your head was okay. But we would quarrel again if I said so, so I asked—

"Something like that. So tell me."

"Oh! ~ What should I do ~ You want to know that much ~"

...For an elder brother, it was very hard to endure, thus I wanted nothing more than to leave her and go back to my room.

"If you don't want to tell me then it's fine."

"Hey hey, I never said that! Why did you give up so easily! Shouldn't you be more patient?"

Seeing that I was about to give up, she quickly called me back.

This girl...if you wanted to boast about it so much, then don't act so superior. Just say it.

"...Tch, forget it. Although I don't like your attitude, consider this a special service, I will tell you."

"Alright alright alright, thank you very much."

We sat down on the sofa, each of us took a side, with an empty space in the middle.

"So, since it's not about new eroge, did you get a new job?"

"Yes! Like that! Look look, this time it's so amazing!"

"Ah ~ if you say so, then it must be very amazing."

"Hohehehehe...yes yes!"

Kirino moved closer and happily showed me the picture on her cell phone.

"Tada! My Little Sister X Railgun Collaboration Project! 'A Certain Crossover Girls' Talk.' I'm gonna have a girls' talk with Mikoto-san at Nico Anime! How is that! Awesome! So amazing!"

"Er? That..."

"Ha? What is with your ultra-low reaction?"


"What's Nico Anime? Who is Mikoto? Some kind of idol or something?"

"Totally wrong! Well, in some ways she is an idol, but it's not quite like that. Ah—really, 'A Certain Scientific Railgun'—I introduced you to it before!"

"You did...? Well, I remember that those guys from the game research club watched that anime too..."

"Ha...can't be helped. Then, I will be extra lenient and tell you in a way that even an idiot can understand."

And so, the extra-lenient Kirino pressed a few buttons on her cell phone and showed me an anime.


"This is Niconico Animation Website, or Nico Anime for short. This is the anime 'A Certain Scientific Railgun,' the main protagonist is Misaka Mikoto! How was that? Cool, wasn't it?"

"Well, she does look quite good, and seems like she has a strong body too."

"I know, right?"

At first look, she was about the same age as Kirino. Natural brown hair, a skirt with shorts underneath. On her legs were loose socks. Ah...what a unique fashion sense.

"Who is this girl with long black hair over here?"

"Ruiko Saten."

"What a cute girl—ouch! That hurts!"

Don't suddenly pull my face, you brat!

"You damn lolicon! Don't you always say that you have no interest in young girls?"

"I have no dirty thoughts, you are overthinking!"

"Hmph, who knows?"

"By the way, why does this girl have flowers on her head?"

"Ah? Who...knows?"

If someone as knowledgeable as Kirino didn't know...it really was mysterious.

"Well...anyway, I got it. In short, Nico Anime is going to make a 'My Little Sister Can't Be This Cute' and 'A Certain Scientific Railgun' crossover project, and you and Mikoto-san are going to join, is that right?"

"That's right! A live show on Niconico."

"Wow, isn't that amazing?"

"That's what I have been saying."

I see. So that's it.

"Since both of us are Dengeki Bunko heroines, I've always wanted to meet Mikoto-senpai at least once."

To make even Kirino respect someone so much, what was so special about her—

"She has 9972 cute little sisters! Mikoto is so amazing! Ehehe, if we become friends, she might introduce them to me!"

"So that's the reason!? You respect Mikoto-san only because of that?"

"She is cute, but her little sisters are cuter! With a cool hat, sexy number #10777 is so brave and so moe! And there is Misaka Worst, who looked so mean, yet she made my S-self want to take a peek at her. However, the cutest one that I want to meet most is Last Order!"

"That's enough! Stop! I get it, your excitement has been conveyed to me!"

Hey hey, you are way too close to me. Really, this girl...she acted like she hated me, but when she talked about something she liked she always ended up like this.

I forcefully stopped my excited little sister's hands and said:

"Looks like it's going to be an exciting job. That's good."

"Yes! I'm very happy!"

What a rare honest answer. My heart skipped a beat.

Right...as long as I could see this happily smiling expression on my little sister's face, I should thank that Misaka Mikoto girl.

"Then, do your best."

"Ha? What are you saying like it's none of your business? Of course you are going to take part in it too!"


What are you saaaaaaaaaayinggggggggg—!
